linux-howto

http://ubuntuforums.org – hi, i installed ubuntu 11.10 after spending some time with Arch and Gentoo (DIY distro sounds good but theres always something to overlook/forget) anyways i have BTRFS / and /home partitions (ext2 /boot) and just added compress=lzo to my fstab to see if there was a noticeable performance gain (after a few updates all the files should have been modified and therefor compressed right?) so my options look something like this: defaults,compress=lzo,subvol=@ is there a way to test if the new mount option has taken effect? also does anyone know of a trick to get btrfs to compress all my stuf (Hardware)

When using the compress mount option, there's usually a message in dmesg with btrfs recognizing that compression is enabled.I guess one way to confirm compression is enabled is to do something likedd if=/dev/zero of=file bs=1M count=1024 btrfs fi sync /btrfsmountpoint du -h file then check the file size.Also, I think it should be lzo and not Lzo.

The idea of subvolumes defeats the purpose of separate partitions, those are soo 2001.Format it with GPT, create a subvol for / so you can do easy snapshotting and fallback.Don't put /var into a separate subvol as it contains your pacman db.But definately one for /home.And compress=lzo for all of them, the compression is smart and will not bother trying to compress things that can't be c

My root filesystem is btrfs, on device sdc1, subvolume "@root", which is also the default subvolume:

Code: :~$ mount -l /dev/sdc1 on / type btrfs (rw,compress) -snip-

:~$ sudo btrfs subvolume list -a / ID 256 gen 18200 top level 5 path <FS_TREE>/@root -snip-

:~$ sudo btrfs subvolume get-default / ID 256 gen 18202 top level 5 path <FS_TREE>/@root

:~$ ca

When I compress files, I expect two basic options. None of which are present in Nautilus's "compress..." context menu action, and instead there is only option to set password. So thought to ask for some solution if someone has already solved this nicely.

Most important to me:

1 - compression level

Because often I just want to store files fast.

Ok.. whats going on here :s

Im trying to run a yum update but getting stopped by dependencies.

So what I wanted to do is compress files (using 7zip) and split a 600MB folder into 199MB parts, but sadly when I tried to do this task with archive manager it gave me an error, but I know that if I use terminal it will work.

Good morning,

I have a file that is 200 MB and I want to compress it to the fullest, which is the best method or command to compress files in aix?

Thank you very much and best regards.

I have access to a server via SSH, I download files from it over SFTP or HTTP. I want to pull down a 4.4GB .mkv file but I have limited bandwidth.

I have used zip, gzip and p7zip, but the file is always 4.4GBs after the compression process. After fiddling with some of the CLI args I managed on one attempt to get the file down to 4.3GBs.

Step 1: I wanted to Add a menu as "Compress as ZIP" on right click. I know i can use change default compress format as "ZIP" using gconf-editor. But I wanted to add a new Menu Item for Compressing as ZIP without opening any other option dialog.

Step 2: I wanted to Compress a file as ZIP and Rename it as a "epub".

Please let me know is it possible to zip&rename by adding single menu Item? Im
